Default Send SMS in C# options (store sms in SIM card)

Hi all,

I am using the code to send sms with compact frame available in MSDN (http://msdn.microsoft.com/library/de...tcfsendsms.asp).

The problem is that I can't set it up so that the received SMS would be stored in the SIM card. It only flashs in the screen.
I need to use PS_MESSAGE_CLASS3 but it is using PS_MESSAGE_CLASS0 and I don't know how to change it.

Can anyone help me, it's very urgent?

Pedro
